IMPROVEMENT IN HARROWS.

Specification forming part of Letters Patent No. 133,212, dated November19, 1872.

making a part of this specification.

The nature of my invention consists in the construction and arrangementof a harrow, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure 1 is a plan view, and Fig. 2 a side elevation of my harrow.

A represents a center beam, at or near the front end of which are topand bottom crossbars B B. On each side of the center beam A, between theends of the cross-bars, is pivoted a side beam, 0.. A short distance inrear of the cross-bars B B, on the beam A, are similar but shortercross-bars B B, having other side beams O O pivoted between them---oneouter side beamsO is pivoted a similar link, D, which extends inwardover the said screwbolt on underneath the link D, and the whole fastenedby means of a lever-nut, E, a washer, I), being first placed underneathsaid nut on the bolt. By this means the side beams O G and O C may beplaced at any angle with the center beam that maybe desired, or, inothor words, their rear ends may be extended or contracted at will. Uponthe outer sides of the side beams are fastened a series of teeth,

G G, constructed as shown in Fig. 2, their upper ends being slottedlongitudinally, and a screw, cl, passed through said slot into the sidebeam and a washer, c, is placed on said screw between its head and thetooth. By this means the teeth may be raised and lowered at will, andalso set at any angle slanting either forward or backward. The teeth mayalso be reversed if desired. Cultivator-teeth J J, having their upperends .or shanks slotted the same as the barrow-teeth, may be attached tothe-inner side beams G O in the same manner, so that by removing theouter side beams O O I will have a combined harrow and cultivator. Hrepresents the handle attached to the center beam A.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-- The reversible and adjustableteeth G G and J J, slotted as described, and fastened by means of screwsd d, substantially as herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this20th day of August, 1872.
